Renal Colic Management

Pain Management

• For patients with suspected kidney stone and NSAID allergy, opioids are a safe and effective alternative analgesic option, providing effective analgesia when NSAIDs are contraindicated, as recommended by the National Comprehensive Cancer Network and MMWR Recommendations and Reports 1, 2
• IV acetaminophen can be considered for more rapid onset of pain relief, with a maximum dose of 4g/day, as suggested by the World Journal of Emergency Surgery 3
• COX-2 inhibitors should not be used in patients with NSAID allergy due to the risk of adverse effects, as stated by the American Journal of Kidney Diseases 4

Medication Dosage

• IV morphine can be administered at a dose of 0.1 mg/kg (typically 5-10 mg) for pain management in renal colic, and IV hydromorphone can be administered at a dose of 0.5-1 mg, while oral oxycodone can be administered at a dose of 5-10 mg every 4-6 hours as needed 1

Treatment Approach

• The treatment approach for renal colic should include starting with IV opioid for rapid pain control, continuing acetaminophen as an adjunct, considering adding tramadol if additional analgesia is needed, and adding tamsulosin to facilitate stone passage, as recommended by the National Comprehensive Cancer Network, MMWR Recommendations and Reports, and World Journal of Emergency Surgery 1, 2, 3
• For patients with musculoskeletal pain, paracetamol (acetaminophen) is recommended up to 3-4g/day in divided doses, with similar efficacy to NSAIDs in musculoskeletal trauma, and NSAIDs (naproxen) are recommended as first-line treatment, but should be used with caution in elderly patients due to risk of kidney injury and GI complications, as recommended by the American College of Physicians 5, 6, 7, 8, 9, 10
• Tramadol is recommended for osteoarthritis when first-line treatments are insufficient, with a lower risk of respiratory depression and addiction compared to stronger opioids, but should be used cautiously in elderly patients due to side effect profile, as recommended by the American College of Physicians 6, 8, 9, 11
• Topical NSAIDs are considered when oral NSAIDs are contraindicated or poorly tolerated, providing good efficacy with fewer systemic side effects, particularly in elderly patients, as recommended by the American College of Physicians 10, 11
• Opioids carry risks of adverse events, misuse, diversion, and addiction, and when used, conduct risk assessment for potential misuse, starting with the lowest effective dose and combining short and long-acting opioids if needed, as recommended by the American College of Physicians 6, 7, 8, 9

Non-Pharmacological Interventions

• Specific acupressure and TENS (Transcutaneous Electrical Nerve Stimulation) provide modest pain reduction in patients with musculoskeletal pain, and physical therapy and exercise are strongly recommended for all musculoskeletal conditions, as they are essential for improving function and reducing pain, as recommended by the American College of Physicians 5, 9

Patient Assessment and Management

• When evaluating a patient who appears to be drug-seeking, conduct a thorough objective assessment for evidence of pain, and look for signs of legitimate pain such as facial expressions, body movements, and functional limitations, as recommended by the American College of Physicians 12, 8
• Consider implementing an opioid treatment agreement if opioids are eventually deemed necessary, and schedule regular follow-up appointments to assess treatment response and document all interactions, treatment decisions, and patient responses, as recommended by the American College of Physicians 6, 12
• Acknowledge the patient's pain concerns without judgment and explain that best practice guidelines recommend starting with safer alternatives, outlining a clear treatment plan using non-opioid options and setting expectations about follow-up and reassessment, as recommended by the American College of Physicians 6, 12
• Review the patient's medication history, including checking the prescription drug monitoring program, and assess risk factors for opioid misuse using validated tools, as recommended by the American College of Physicians 12
• Recognize that patients may exhibit "pseudoaddiction" when pain is undertreated, and consider the patient's individual needs and circumstances when developing a treatment plan, as recommended by the American College of Physicians 12, 6
